Frequently Asked Questions

What is an OSG spiral-flute STI tap used for?

An OSG spiral-flute STI tap is used to cut internal threads in pre-drilled holes for screw thread inserts. It is commonly applied in aerospace, automotive, and general manufacturing where strong, wear-resistant threads are needed in softer materials like aluminum or cast iron.

What are the specifications of the OSG M10x1.5 STI tap?

This OSG STI tap has a metric M10x1.5 thread size, a D4 / 4H-6H tolerance class, 3 flutes, and is made from high-speed steel. The spiral-flute design aids chip evacuation in blind-hole applications. The manufacturer part number is 10900800.

How to select the correct OSG STI tap for a thread insert?

Select an OSG STI tap based on the insert's thread size and pitch, such as M10x1.5. Ensure the tap tolerance class (e.g., D4 / 4H-6H) matches the required thread fit. Use a spiral-flute design for blind holes and a straight-flute for through holes. Always follow the insert manufacturer's drilling and tapping recommendations.
